REVOLVING AND SLIDING CHAIR.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed. December 22, 1906, Serial No. 349,135. RenewedSeptember 11, 1908; Serial No. 452,658.

To all whom it may concern:

Be it known that we, ROBERT W. BUTCHER and JOHN L. PERmN, citizens ofthe United States, residing at Manila, in the Philippine Islands, haveinvented new and useful Improvements in Revolvin and Sliding Chairs, ofwhich the following 1s a specification.

' This invention relates to chairs and more particularly to that classof chairs designed for use on shipboard.

One of the principal objects of the invention is to provide a revolvingand sliding chair which can be used to advantage in seating persons atthe dining table or in other places where it is desirable to movethe'chair up toward the table or desk.

Much inconvenience has been experienced on shipboard and in other placeswhere chairs are mounted upon pedestals secured to the floor or deck andbeing thus immovable toward and from the table for the reason that ifthe pedestal is located too closely to the table, it is difiicult for apassenger to get into the seat, while on the other hand if the pedestalis located at some distance from the 'table considerable inconvenienceis experienced owing to the necessity of leaning over to assume acomfortable position next to the table.

One of the objects of our invention is to overcome the inconveniencesreferred to and to that end we have provided means whereby the chair orseat maybe revolved upon its pedestal and moved toward and from thetable either by the person after he has taken his seat or by the waiterat the back of the chair.

The objects and advantages referred to may be attained by means of theconstruction illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of a chair or seat made in accordance withour invention. Fig. 2 is a horizontal section on the line 2-2, Fig. 1,and showing an underside plan view of the seat. Fig. 3 is a plan View ofthe upper member of the turn-table. Fig. 4; is a similar View of thelower member thereof. Fi 5 is a detail section on the line 55, of Fig.3.

Referring to the drawings for a more particular description of ourinvention, the numeral 1 designates the pedestal upon which therevolvingand sliding seat is mounted. This pedestal may be ofanysuitable construction but as shown, comprises a base portion 2 designedto be secured by screws or bolts to the floor or deck and rising fromsaid base is a tubular standard 3 having radially projecting curvedflanges or wings 4. Secured to or formed upon said wings 4 isthe lowermember 5 of the. turn-table, said member 5 consisting of a fiat ring orannulus provided with peripheral recesses 6, three of such recessesbeing shown in the drawings but any suitable number may be employed. Theupper member 5 of theturn-table consists of a ring or annulus havingthree inwardly extending lips 7 formed upon flanges bent downward fromthe member 5, said lips engaging the periphery 8 of the member 5 betweenthe recesses 6 to permit the member 5 to rotate freely on said member 5.The member 5 may be removed from the member 5 by bringing the lips 7into coincidence with the recesses 6, as will be understood. Formed intheupper member 5 of the turn-table are a number of screw holes 9 uponopposite sides of said member and secured by means or flanges 13 toengage the flanges 13 of the rails 11. The rails 11 are secured to theunderside of the seat a by means of screws 12 and a stop 14 upon saidrails 11 serves to prevent the rails 11 from being moved .too .far or topermit the removal of the seat when sliding the same outward.

. Pivotally mounted underneath the seat are a pair of operating levers15, said levers being pivoted at 16 and passed through keepers 17 andprovided with suitable han dles 18. A bolt or dog 19 is connected at 20to each of the levers 15, said bolt passing through a keeper 21 securedunder the seat. The ends of the bolts 19 engage the notches 10 in therail 11 and when the handles 18 are moved-outwardlyagainst the tensionof the springs 22, the seat a may be moved outwardly and inwardly towardand from the table, as required.

In order that the seat may be moved by the waiter at the back of thechair a pair of levers 23 pivotally connected at 24 and connected attheir outer ends to the levers are provided and mounted in a guideway atthe back of the seat is a button 25 connected to the levers 23. Theshank 26 extends into' the gateway in the rear of the seat, and a spring27 bears against the shank 26 to throw the levers 23 and the button 25outward. The button 25 may be operated by the knee of the waiter.

The operation of our invention may be briefly described as follows: Theseat a may be rotated-to bring the front portion of the seat outwardaway from the table and when the person, sits upon the seat it may ber0- tated to face the table and then it may be slid forward toward thetable by means of the handles 18 being actuated to release the bolts 19from the notches 10 or by means of the push button 25 from behind thechair. It will be understood that the chair can be freely rotated andwill be locked against the sliding movement by means of the bolts 19 andthe'notches 10 until the handles 18 or the button 25 are moved, when theseat may be moved inward or outward as required.

From the foregoing it will be obvious that our invention is ofcomparatively simple structure, cannot readily get out of order, isstrong and durable, and can be quickly operated to move the person up toand away from the table either by himself or, by a Waiter or person atthe back of the chair and that when moved to the desired position theseat is locked in place auto-= departing from the'spirit and scope ofour invention. 7

Having thusdescribed the invention, what we claim is: 1

1. In a chair, a pedestal, a turn table member secured thereto andprovided with peripheral recesses, a turn table member provided withinwardly extending lips adapted to be brought into coincidence with saidrecesses to remove the last'mentioned turn table member, guide barssecured to one of said members, a seat, guide bars secured to said seat,whereby the latter may be moved inward and outward upon the pedestal,means for. locking the seat in its adjusted position, levers foractuating the locking means, and a spring seated push button forunlocking said levers.

2. In a revolving and sliding seat, a pair of guide bars upon which theseat may be moved, one of said guide bars being provided with notches,spring actuated pivoted levers carrying bolts to en age said notches,handles upon said levers f or operating said bolts, a turn table memberprovided with peripheral recesses, a turn table member provided withinwardly extending lips adapted to be brought into coincidence with saidrecesses to-remove the last mentioned turn table member, one of saidturn table members being'carried by the seat and the other beingsupported upon the pedestal.

In testimony whereof, we aflix our signatures in presence of twoWitnesses.
